CIGARETTE-MAKING MACHINE.

Application filed October 22, 1925, Serial No. 64,225, and. in GermanyNovember 4, 1924.

The devices used hitherto in cigarette making machines for depositingcigarettes in regular rows have various defects, which for instance inone constructional form result in the cigarettes being thrown from theiroriginal path of travel too quickly on to the band of the receiver, thuscausing the ends to be damaged and preventing the cigarettes from beinglaid smoothly and regularly in rows. In another constructional form, inwhich the cigarettes are' laid smoothly on to the band, for instance bymeans of the vanes of a rotating drum, the cigarettes are not separatedfrom one another by spaces, which, on their being pushed out of theiroriginal path on to the bandof the receiver, results in the cigarettesrubbing against one another and being thereby damaged. In additionthereto the removal of the cigarettes from the band of the receiverentails serious inconvenience, as between two rows of depositedcigarettes there is 'suflicient space. In a third constructional formthe cigarettes are separated from one another by spaces, but the pushingof them on to the band of the receiver is effected by an inclined wall,which has the disadvantage that the original correct posltion of thecigarettes is. altered. Devices, in which the removal of the cigaretteson to the band of the receiver was to be efiected by air pressure havenot been adopted in practice apparently owing to inconvenience.

The device according to the present invention, the object of which is todo away with all the difficulties referred to, is shown in theaccompanying drawings, in which Figure 1 is a horizontal longitudinalsection, at right angles to the cigarette, Figure 2 a verticallongitudinal section parallel to the cigarette, Figure 3 a side viewlooking at the band and the roller located above the same, where thecigarettes are first received, and Figure 4 a plan view of the entiredevice. The new device and its manner of operation are described in thefollowing: The finished cigarettes, 1, 1 which are ided by the gutter 2,pass on to the distri uting band 3 which runs round the pulley 5 and theroller 6, the pulley 5 receiving its rotary motion by means of toothWheels 29 and 30, the shaft 31 and a pair of bevel wheels 32 and 33 fromthe common shaft of the ma chine and imparting to the band 3 a quickermotion than the motion of the cigarettes along the gutter 2, whereby thecigarettes,

after reaching the band 3, commence to move more rapidly than was thecase along the gutter 2; In order that the cigarettes shall receive oneafter another quickly and uniformly the'speed of travel of the band 3, aroller 4 is mounted above them, which is driven from the roller 6 bymeans of the belt 7 (Figures 3 and 4) and presses the cigarettes lightlyagainst the distributing band 3. The shaft of the roller 4 is journalledin the lever 8 which rotates freely on the shaft 9 of the holder 10. Ascrew 11 is provided for regulating the pressure of the roller 4 on thecigarette. After a more rapid forward motion has been imparted to thecigarettes 1, 1 by the band 3 of the roller 4, the cigarettes will moveon the band 3 with spaces between, as is shown in Figures 2 and 4, andin this position are pressed by the band 3 on to the bands 13 and 12 ofthe receiver for the finished cigarettes by means of the pusher 14 andare deposited in regular rows 1, 1 The pusher 14 travels along a pathindicated in Figure 1 by dotted lines occupying successively theositions 14, 14, 14 and 14 and thereby pus ing during its forward motionthe cigarettes 1, l on to the bands 12 and 13, While during its returnmotion it rises and makes way for the following cigarettes. This motionis imparted to the pusher by means of the 'lever 15, to which it isfixed. The lever 15 has two motions imparted to it: a reciprocatinmotion in a straight line, parallel to itself, along with the slide 20by means of the roller 21 and the eccentric groove 22 of the eccentric19 and a circular motion about its own axis 16 by means of the roller 17which runs in the groove 18 of the same eccentric.

The pusher 14 displaces the cigarettes 1, 1 at the moment, at which oneof the same arrives at the edge 23 and the other at the edge 24 of theplates 25 and 26, which lie below the band. The bands 12 and 13 arestretched over the pulley 27 and the roller 28, the pulley 27 receivingits rotary motion by means of the bevel Wheels 34 and 35 and the spurwheels 36 and 37 from the shaft 31.

The eccentric 19 is .fixed on the shaft 38 (Figures 1 and 4) which isrotated b means of the bevel wheels 39 and 40 from t e shaft 31. Theeccentric 19 w ith all the parts which impart motion to it and thetoothed wheelsa29 and 30 are housed in the casing 41 which ishermetically sealed by the cover 42. The lever 15 is in the casing'ofthe slide 20, which is hermetically sealed by the cover 48. In Figure lthe covers 42 and 43 are removed, in order that the mechanism housed inthe casings 41 and may be visible. The shaft 31 and all the parts, fromwhich it receives its motion or towhich it transmits the same, arehoused in the hermetically closed casing 44. Thus all the mechanismswhich impart motions to the working parts of the device are inhermetically closed casings, where they operate under the mostfavourable conditions as regards lubrication and are completelyprotected from dirt and dust.

It will be clear from what has been said above that the cigarettes aredeposited smoothly and without any damage in regular rows and also thatwhen the cigarettes are provided with tips stuck on with an adhesive(cork and the like) the position of the ends having the tips will remainunaltered, when the cigarettes are deposited on the receivin bands 12and 13.

What I c aim is 1. In a cigarette making machine means for depositingcigarettes in regular rows,

Lesaaea spaces between successive cigarettes, as set forth.

2. In a cigarette making machine means for depositing cigarettes *1nregular rows, comprising in combination a smooth distributing band aroller lying above the said distributing band for bringing each finishedcigarette on to the surface of the said band and for increasing thespeed of travel of the cigarette, for the purpose of forming spacesbetween successive cigarettes, a lever, a pusher on the said lever, anda double eccentric for imparting two motions to the said lever, namely aforward motion for pushing the cigarettes from the distributing band anda circular motion for raising the pusher on its return movement, as setforth.

In testimony whereof I have signed my name to this specification.
